You're definitelly going to poke me about it later, since the DM will cause a 
size growth. There's no discussion about it and it's a simple fact we have to 
face and accept. If we're going to hunt every kb of growth, we can flat out stop 
the DM and give up, sorry.

Here are some measurements, but they're not final. Something grew a bit and 
something did not grew:

Configuring for omap3_beagle board...
   text    data     bss     dec     hex filename
 326912    8648  266944  602504   93188 ./u-boot
 326657    8764  266792  602213   93065 ./u-boot
  45794    1860  198020  245674   3bfaa ./spl/u-boot-spl
  45817    1868  198020  245705   3bfc9 ./spl/u-boot-spl

You see the SPL grew, U-Boot shrunk. But the size difference is of tens of bytes 
magnitude.

Configuring for sandbox board...
   text    data     bss     dec     hex filename
 138674    6456   28504  173634   2a642 ./u-boot
 139002    6512   28424  173938   2a772 ./u-boot

Configuring for grsim_leon2 board...
   text    data     bss     dec     hex filename
  97058    3384    2640  103082   192aa ./u-boot
  97106    3448    2592  103146   192ea ./u-boot

Configuring for P1020RDB-PC_36BIT_SPIFLASH - Board: p1_p2_rdb_pc, Options: 
P1020RDB,36BIT,SPIFLASH
   text    data     bss     dec     hex filename
 394550   30940  267600  693090   a9362 ./u-boot
 394601   31068  267536  693205   a93d5 ./u-boot

Best regards,
